Abstract

This paper discusses several phase-retrieval techniques commonly used in fringe-projection profilometry (FPP). The FPP has become a suitable and powerful method for the measurement of object surface shape, and some algorithms have been proposed to extract phase maps, such as Fourier transform profilometry (FTP). In this paper, FTP, phase-shifting and continuous wavelet transform (CWT) are briefly described and discussed. In addition, two-dimensional short-time Fourier transform (STFT) is also presented to extract wrapped phase maps. Simulations and experimental results are presented to show the performance of these phase-retrieval techniques in FPP.
